As we all know,polycarboxylate superplasticizer is new generation concrete admixture.
It can reach 30% water reducing ratio with dosage 0.2% to 0.3%.
To reach 20% water reducing ratio,dosage for sodium naphthalene formaldehyde will be around 0.8%-1%.
Unite price for polycarboxylate superplasticizer 50% is around 1065$ per ton with IBC tank package now,unite price for sodium naphthalene formaldehyde is around 814$ per ton.
Above all,i think that’s why more and more customer change to use polycarboxylate superplasticizer.
Recently we rebuilt our factory,expanded production schedual.our technical department researched new product,like early strength type polycarboxylate superplasticizer used for ready mix concrete plant.from delivery and package saving aspect,we developed 55% ,60% solid content and powder type polycarboxylate superplasticizer.
About usage,when your concrete material is good,you can only use our high water reducing type polycarboxylate superplasticizer.if your cement contain mud,need mix use our high slump retention type and high water reducing type polycarboxylate superplasticizer.
When cement mud content high,water reducing ratio for high slump retention type is higher than water reducing type.
Usually,mixing ratio for water reducer and slump retainer can be 8:2 or 6:4 or 7:3,when you got our sample for polycarboxylate superplasticizer,need test by yourself to find suitable ratio with your concrete material.
